AccreditationWatercare Laboratory Services is IANZ accredited to NZS/ISO/IEC 17025. The laboratories offer a full range of accredited methods for laboratory analyses on water, wastewater, solids, air and other environmental samples. This accreditation ensures that we meet stringent international standards of technical competence, reliability and quality management. All laboratory personnel undergo regular training to comply with the NZS/ISO/IEC 17025 standard.

Our air quality monitoring group operates to the highest international standards, and where applicable, all of our ambient air testing complies with Australia and New Zealand standard methods and the Ministry for Environment’s Good Practice Guide.

Major internal audits are carried out on an annual basis. In addition, Watercare Laboratory Services is peer reviewed by internationally recognised scientists on a regular basis. The laboratory is continuously improving its technology and extending the range of accredited methods it currently offers.
